YouTube launches face-blurring tool to hide identities
Nevertheless, one London-based campaign group welcomed the news.
"Publishing videos online is a very effective way for charities and NGOs [non-governmental organisations] to show the world their work and attract support, but it has historically been difficult to do without invading the subjects' privacy or placing them at serious risk," said Emma Draper from Privacy International.
"Simply identifying certain people in certain situations - refugees, for example, or rape victims - can put them or their families in danger of their lives.
"While some companies are pouring resources into creating more accurate and more pervasive facial recognition systems, it is heartening to see YouTube take a step in the opposite direction."
